There are four main ways to score in rugby league:
Try - four points
A try is worth four points - the maximum number of points you can score in one go in rugby league.
It is scored when a player puts the ball on the ground with "downward pressure" (very important) inside the opposition's in-goal area between the try line and dead ball line.
If a defender makes an offence while the opposition are about to score a try, then the referee can award a penalty kick in front of the posts after the conversion kick.
This means the opposition can score eight points if they are successful in scoring the try, the goal kick and the penalty kick.
But if the try was not scored because of the offence, the referee will award a penalty try in front of the posts, as well as the extra penalty kick.
Goal kick - two points
A team is awarded a goal kick after a try has been scored. The team has the chance to "convert" the kick at goal for two further points.
The kick is taken from a point level with where the try was scored.
The kick is successful if the ball goes between the opposition's goalposts and above the crossbar.
Penalty - two points
The referee will award a penalty when an offence has occurred.
A player can punt, drop kick or take a place kick anywhere behind where the offence took place.
They also have the choice of kicking for goal or for touch.
A kick for goal is worth two points if successful.
But to be successful, the ball has to go through the opposition's goalposts, above the crossbar.
Two touch judges will raise their flags if the penalty is successfully kicked.
If the team who gave away the penalty argue or commit further offences, the referee will punish them by taking the penalty 10 metres forward towards their goal-line.
The team kicking also gets a new set of six tackles to play with.
Play is re-started by placing the ball on the ground 10 metres into the field of play, parallel to where the ball went out to touch.
Teams can kick in any direction even backwards if they want to find space for a set play.
Drop goal - one point
A drop goal can be a spectacular way of scoring. If successful it will add one point to a team's score.
A drop goal is scored when a player kicks the ball from hand through the opposition's goal posts, above the crossbar.
However, the ball must touch the ground between being dropped and kicked.
